Tetanus is an infection caused by the invasion of the body by Clostridium tetani. Clostridium tetani is an anaerobic bacterium and an opportunistic pathogen, which is likely to cause tetanus in conditions such as anaerobic environments, deep wounds, or heavily contaminated wounds. Therefore, in cases where wounds are relatively small yet deep, and are considered to be in an anaerobic environment, or are contaminated with rust or soil, or in situations such as open fractures, blast injuries, gunshot wounds, and animal bites, tetanus injection treatment is necessary. It is generally recommended to administer the injection within 24 hours, and a skin test should be conducted before the injection, with alcohol consumption prohibited.
